Silent (Tyvan/Catnoss) [Book 1]

'He used to be so lively.'
'Why isn't he talking?'
That, plus countless of other things, are what Evan's friends think after their friend returns from a trip home.
'We need to help him.'
'We?!'
But only one friend truly cares about what happened to Evan.
Not his best friend, Jon, but his good old bro-
Tyler.
'What happened?'
Nothing...
'Are you a mute now, Evan?'
...but silence.
